Constructor Detail

### MetaData

    public MetaData(ASN1Boolean hashProtected,
                    ASN1UTF8String fileName,
                    ASN1IA5String mediaType,
                    Attributes otherMetaData)

Method Detail

### getInstance

    public static MetaData getInstance(java.lang.Object obj)

  Return a MetaData object from the given object.

  Accepted inputs: null → null `MetaData` object `ASN1Sequence` input formats with MetaData structure inside

  Parameters:
    `obj` - the object we want converted.
  Throws:
    `java.lang.IllegalArgumentException` - if the object cannot be converted.

### toASN1Primitive

    public ASN1Primitive toASN1Primitive()

  Description copied from class: `ASN1Object`
  Method providing a primitive representation of this object suitable for encoding.

  Specified by:
    `toASN1Primitive` in interface `ASN1Encodable`
  Specified by:
    `toASN1Primitive` in class `ASN1Object`
  Returns:
    a primitive representation of this object.

### isHashProtected

    public boolean isHashProtected()

### getFileName

    public DERUTF8String getFileName()

  Deprecated. Use `getFileNameUTF8()` instead.

### getFileNameUTF8

    public ASN1UTF8String getFileNameUTF8()

### getMediaType

    public DERIA5String getMediaType()

  Deprecated. Use `getMediaTypeIA5()` instead.

### getMediaTypeIA5

    public ASN1IA5String getMediaTypeIA5()

### getOtherMetaData

    public Attributes getOtherMetaData()
